For those who don't know, I am obsessed with NBC's "The Sing Off." I have been since day one and my excitement grew exponentially when my girl Sara Bareilles became a judge.
Last season the winner was a group called Pentatonix. I rooted for them every single week and was over the moon when they took home the title.
Today they prove their champion status once again by releasing an NSYNC medley that begins with NSYNC's popular holiday song. You know the one, you likely have it memorized.

Are you listening again? Yeah, me too.
